Please, tell me - do you think it's reasonable to carry out genital reconstruction on babies for purely cosmetic (and social/psychological/whatever) reasons?
Why the binary choice? It might be pretty dubious to carry out an operation on a child which can't consent to it, but at least the parents of that child could make a decent argument that they're acting in the interests of the child. Circumcision of either gender has no reasoned arguments in favor of it: it only has rationalizations, and weak ones at that. About the best you can hope for is that the effects on the child are neutral.
